     Make sure that Pretty.text is inlined in stage 0,
     so that RULE text/str gets a chance to fire (Trac #7995).

     And make sure that Outputable.text is inlined, so that the underlying
     Pretty.text rule can fire.

     The thing is that literal strings only turn into unpackCString#
     in phase 1.
